NC Barrier Island Road Networks

Analysis of NC barrier island road networks.

This set of notebooks is based heavily on an existing repository: https://github.com/envidynxlab/Networks_Barriers

and the resulting (OA) paper in Earth's Future: https://doi.org/10.1029/2021EF002581

The goals of this repository are to further analyze NC barrier islands:

• go beyond bathub flooding and use flooding based on event forecasts (existing ADCIRC model runs)
• incorporate other metrics beyond elevation (i.e., distance to coastline, fronting dune height, etc.)
• test with real time traffic logs

To reproduce the analysis, follow these steps

Step 0: set up the environment

> conda create -n roads

> conda activate roads

> conda install -c conda-forge fiona gdal networkx osmnx requests scipy urllib3 zipp shapely rasterio geopandas pandas numpy matplotlib notebook tqdm contextily -y

Note that an `environment.yml is also included in the repository.

Step 1: run getNCBarriers.ipynb to get the barrier shapefiles

Step 2: run getNCCUDEM.ipynb to get the elevation data (CUDEM)

Step 3: run getExceedence.ipynb to get the water level data (NOAA)

Step 4: run getRoads.ipynb to get the road data (OSM)

Step 5: run doAnalysis.ipynb to analyze the assembled data
